摘要
本文对广东省国营增城林场的马尾松、黎(?)栲混交林与马尾松纯林的土壤养分、微生物生理群数量、生化强度和酶活性等肥力因素进行了研究,结果表明:在18个土壤肥力因素中,混交林育群,纤维素分解作用、蛋白酶活性,混交林与纯林有显著差异;而这两类林地土壤微生物生理群数量及其生化强度的季节性交化规律大致相似,但养分和酶活性的变化规律相差较大。
IP.this paper were investigated soil fertility factors,such as the quantity of microorganisms,the biochemical and enzymatic activities and the nutrient in the mixed forest of Picus massoniman and Caslanopsis fissa of Zengeheng Forest Farm,Guangdong Province.Among the 18 fertility factors investigated the annual average of 14 factors in the mixed forest is higher than those in pure forest of P.massoniaus.This shows that the mixed forest gets obviously higher fertility level of soil than the pure forest does.Comparing the mixed forest with the pure forest,the seasonal quantity and activities of microorganisms in soil are nearly equal to each other,but the nutrient and the enzymatic activities very differ.
